This is the fun part. Take the crane by the wire end, and fully submerge it into the can of Plasti Dip. Make sure about an inch of the wire is covered as well.
I'm using a gallon can of Plasti Dip. If you are using a smaller sized can and your crane's wingspan is too wide, you can pour the Plasti Dip into an empty coffee can (or something similar). You may also need a tool to help fully submerge the crane into the Plasti Dip. I used a plastic knife.
Slowly pull the crane out of the dip and let the excess rubber drip off.
